Exhibit D - Mining Plan <br /> terrace of Section 29, the soil has been enhanced by the establishment of pasture grass that has <br /> developed a good organic base in the upper 6.0±to 12.0±inches of the solum. <br /> The native A profile of the upland terrace is predominantly modified as a plow layer of 6.0±to <br /> 10.0±inches, regardless of the soil unit description. The historic practice of incorporating manure <br /> into the plow layer should have served to maintain the organic base and quality of the cropped <br /> soils. Since the cropped soils have been irrigated,care should be taken not to salvage soils greater <br /> than 12.Ot inches in depth to avoid mixing of potential accumulated salts. Soil testing at varying <br /> depths should occur over the property to build a soil datum to assure adequate soil quality for <br /> reclamation and to prevent mixing of surface soils with soil horizons potentially greater in the level <br /> of accumulated salts due to years of irrigation practice over the affected soils. <br /> Generally, total overburden depth over the property is approximately four [4.0t] feet, with a <br /> gravel depth to shale varying 15.0±to 40.0±feet over the entire property. Site geology is typified <br /> by mixed alluvial and aeolian development, that is predominantly alluvial in nature, with <br /> groundwater varying from one foot below the surface in the wetland portions of the lower terrace, <br /> to 7.0±to 10±feet along portions of the upper terrace. <br /> Plant Site Development: Precedent to extraction activities, a basin will be extracted in the <br /> NorthWest comer of Section 28 11), to function as recycling wash water and receiving basin for <br /> reject fines for the intended Plant/Processing activities (11 and III). Since the basin will need to <br /> be excavated in a dry state, the site (1) will need to be dewatered. <br /> Up to two settling basins will be established on Section 29 to facilitate clean water discharge under <br /> an approved Colorado Department of Health Storm Water/Process Water Discharge Permit. <br /> Since the settling ponds are essentially smaller, they can be excavated wet and avoid potential <br /> discharge of suspended solids since there is a chicken and the egg problem of creating yet another <br /> settling basin for a settling basin. <br /> Regardless, once the settling basins are established,the wash pond 11) can be created. Once <br /> established, the settling basins will only be needed when cleaning out the wash pond solids for use <br /> as fill,product, or use as a soil/soil amendment. Otherwise, it is the intent to recycle wash pond <br /> water as a closed system. <br /> Plant equipment will be established at II and III and includes [but is not limited to] the set up of a <br /> crusher, screens, and conveyors, scale house and attending equipment. Plant equipment will also <br /> include the establishment of asphalt and concrete batch plant operations. Resulting stockpiles of pit <br /> run and processed products will occur over II and III. <br /> As previously stated,plant activities will require a wash plant and attending wash pond to recycle <br /> wash water and receive discharge silts and other reject fines from the washed product. Plant and <br /> Wash Pond areas are identified on Exhibit C- 2: Mine Plan Map. All water requirements and <br /> sources for the operation are identified under Exhibit G-Water Information, and will be in <br /> conformance with all requirements of the Colorado Division of Water Resources -Office of the <br /> State Engineer. <br /> Ultimately, the closed system wash pond will fill with silt and be revegetated in a manner <br /> consistent with Exhibit E- Reclamation Plan. Interim clean out of the wash pond will occur, <br /> returning the inert materials to the bottom of exhausted pits, or utilizing it in part or in whole as <br /> product, or for purposes as substitute soil, soil additive, or as subsoil for reclamation. Silt or other <br /> reject fines from the wash pond that are used for reclamation will be soil tested for suitability prior <br /> to use, and all tests will be included in the Annual Report to the DMG. <br /> EXHIBIT D- Mining Plan 2 <br /> Colorado Division of Mineral s & Geology Regular Impact [1121 Construction Material Permit <br /> Sand Land, Inc. - Kurtz Resource Recovery & Development Project -January 1999 <br />
